fa Influence of low-intensity laser therapy on the stability of orthodontic mini-implants: a study in rabbits جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Objective</strong></p><p>  The objective of this study was to assess stability of different orthodontic mini-implants in the tibia of rabbits after low-intensity laser therapy. <strong></strong></p><p> <strong>Material and methods</strong> </p><p> Thirty-two mini-implants were assessed, 16 were self-threading (Titanium Fix) and 16 self-perforating (INP). These were inserted into the tibia of rabbits and immediately loaded with a horizontal force of 200g uniting 2 mini-implants in each tibia. Then they were submitted to low-intensity laser therapy for 21 days. Sixteen male New Zealand breed rabbits were used, and divided into 2 groups of 8 animals each as follows: Groups INP and TF. In both groups, mini-implants were submitted to low-intensity laser therapy (right tibia) and their respective controls (left tibia) did not undergo laser therapy. After the animals were killed, blocks of bone tissue containing the mini-implants were removed so as to perform mechanical pull-out tests. </p><p> <strong>Results</strong> </p><p> There was a statistically significant difference only between Group TF submitted to laser and all the other groups (P < .05). </p><p> <strong>Conclusions</strong></p><p>  Low-intensity laser was capable of increasing stability of self-threading orthodontic mini-implants. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p><a href="http://www.oooojournal.net/article/S2212-4403(12)00123-X/abstract" target="_blank"><font color="#0000ff"> Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1522&slc_lang=fa&sid=1 Mardônio Rodrigues Pinto 10031947532846006970 10031947532846006970 No Federal University of Rio de Janeiro, UFRJ, Rio de Janeiro, Brazil Rogério Lacerda dos Santos 10031947532846006971 10031947532846006971 Yes Federal University of Campina Grande, UFCG, Paraiba, Brazil Matheus Melo Pithon 10031947532846006972 10031947532846006972 No Southwest Bahia State University - UESB, Bahia, Brazil Mônica Tirre de Souza Araújo 10031947532846006973 10031947532846006973 No Federal University of Rio de Janeiro, UFRJ, Rio de Janeiro, Brazil João Paulo Viana Braga 10031947532846006974 10031947532846006974 No Federal University of Rio de Janeiro, UFRJ, Rio de Janeiro, Brazil Lincoln Issamu Nojima 10031947532846006975 10031947532846006975 No Federal University of Rio de Janeiro, UFRJ, Rio de Janeiro, Brazil
